1. 1. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

   University essay from Högskolan i Gävle/Samhällsbyggnad

   Author : Mathias Billenberg; [2023]
   Keywords : TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

   Abstract : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. READ MORE

3. 2. Estimation of Site-Specific Biomass and Leaf Area Index in a Young Scots pine Stand in Southern Sweden

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Olamide Michael Adu; [2023]
   Keywords : Scots pine; Biomass estimation; Leaf area index; Model validation; Site-specific models;

   Abstract : Accurate biomass and leaf area index (LAI) estimation are crucial for understanding forest productivity and carbon dynamics. Models are crucial to estimating forest biomass and LAI. This study aimed to estimate site-specific aboveground biomass and LAI in a young Scots pine stand in southern Sweden. READ MORE

4. 3. Forest Aboveground Biomass Monitoring in Southern Sweden Using Random Forest Modelwith Sentinel-1, Sentinel-2, and LiDAR Data

   University essay from Högskolan i Gävle/Samhällsbyggnad

   Author : Wan Ni Lin; [2023]
   Keywords : Aboveground biomass; Sentinel-1; Sentinel-2; LiDAR; random forest; GEE;

   Abstract : Monitoring carbon stock has emerged as a critical environmental problem among several worldwide organizations and collaborations in the context of global warming and climate change. This study seeks to provide a remote sensing solution based on three types of data, to explore the feasibility and reliability of estimating aboveground biomass (AGB) in order to improve the efficiency of monitoring carbon stock.

5. 4. Using Sentinel-2 Satellite Images to Estimate Traits of Forage Grasslands

   University essay from SLU/Dept. of Agricultural Research for Northern Sweden

   Author : Niklas Zeiner; [2021]
   Keywords : Remote sensing; Forage grasslands; Sentinel-2; Dry matter yield; Canopy average height; Total leaf chlorophyll content; Partial least squares; Support vector machines;

   Abstract : In this project, regression models based on data from field measurements and spectral information extracted from satellite imagery were used to estimate traits of forage grasslands; dry matter yield, canopy average height and total leaf chlorophyll. Four fields at SLUs Röbäcksdalen field station were sampled on 22 occasions and a total of 198 samples, including measurement of the highest plant, canopy height, leaf chlorophyll content, canopy spectral reflectance and biomass were collected.

6. 5. Carbon Stability of Biochar : Methods for assessment and indication

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Helena Söderqvist; [2019]
   Keywords : Biochar; Stability; MRT; Carbon sink; Carbon stability; Negative emissions technology NET ;

   Abstract : Biochar can reduce the amount of CO2 in the atmosphere and is acknowledged as one feasible technology for negative carbon emissions. The stability of carbon in biochar is of major importance for the carbon sequestration value. A method for confident estimation of the stability is needed to make efficient priorities for the climate. READ MORE
